Detailed Description

This is a temporary data structure used in building the local-global DOF maps. It distributes the DOFs among all cells, not just the cells that will be integrated. This data structure is huge, but it gets deleted before the matrix is built.

Initially, all cells are tagged with -1, which indicates that they have not yet had a DOF number assigned. DOF indices are assigned during calls to the appendDOFs() method; if a cell is not locally owned, that cell's global index is appended to a table of requests to be resolved by other processors. Remotely owned cells are tagged with -2. That tag is never used in calculations, but can trap errors if some cell never gets resolved.

Once all the local DOFs have been assigned and the remote cells have been identified, call synchronizeRemoteDOFs() to share DOF counts across processors and resolve DOF numbers for remotely owned cells.

Finally, after the remote DOFs have been resolved, we can make calls to the getDOFs() methods to get DOF indices for (cell, funcID) sets.
